SAMUEL A. IRVIN, OF DAYTON, OHIO.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 242,205, dated May 31, 1881.

Application filed November 1, 1880.

To all whom it may concern:

Be it known that I, SAMUEL A. IRVIN, of Dayton, in 'the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Window-Screens, of which the following is a specification.

My invention relates to notched openings in the side of the top rail of the frame, partly covered by the wire-cloth and closed by a slide moving longitudinally, which has notches corresponding to those of the frame.

Figure 1 is a rear elevation of the windowscreen. Fig. II is an under view of the top rail. Fig. III is a vertical section through line 00 m, Fig. I.

A represents the frame, which is nmrtised together in the usual manner. 7

O C are slats supported in grooves plowed in the sides of the frame, and are thrust out by spiral springs arranged behind them.

The wire-cloth D is tacked on on the outside of the frame to cover the entire opening of the frame, and over the edges of this ciothis tacked the molding E. In the upper rail the timber is cut away, thus forming quadrangular notches extending from the lower edge of rail to the edge of the molding. The wire-cloth has corresponding notches which cover about (No model.)

half of the space in the frame. That the wirecloth may be held snugly to the rail, it is tacked on the sides of the orifices.

At Fig. II are shown the orifices as they appear from beneath the rail, the slide B covering all but one, thus illustrating the manner of closing them.

In Figs. I and II is shown the notched slide, which is held in position by pins entering lengthened slots or mortises. The slide has a knob for convenience in handling.

The operation is thus: Move the slide to the right, and there are a series of open orifices through the frame and the screen. This admits of insects passing freely through from within to the outside. Move the slide to the left and the passages are closed, and the ingress of insects is impossible.

What I claim as my invent-ion and desire to secure by Letters Patent, is-

The Window-screen A and the wire-cloth D, havingorifices,incombination with thenotched slide B, substantially as shown and set forth, and for the purposes specified.

SAMUEL A. IRVIN.
